Wrong width for the zero width no-break space (ZWNBSP) or byte order mark (BOM) character u+feff.

[edward-dauvergne]

Hopefully this is enough to reproduce:

>>> import wcwidth
>>> a = u"3\ufeff4"
>>> wcwidth.wcswidth(a)
3
>>> a
'3\ufeff4'
>>> print(a)
34
>>>

Rather than:

>>> wcwidth.wcwidth(u'\ufeff')
1

I would expect:

>>> wcwidth.wcwidth(u'\ufeff')
0

This is enough information, I hope to fix this after consulting unicode specification regarding this character.

This is resolved in today's release, sorry for the long turnaround
